The announcement was a surprise, since Bieber is not obligated to take the test. Yeater, 20, had claimed that she had sex with Bieber backstage at an L.A. concert in October 2010, but she dropped her much-scrutinized paternity suit earlier this month.

Braun explained that Bieber "doesn't mind" taking the DNA test. "He's like 'I'm just going to go ahead of it and be fine.'"

But Bieber's team is still considering legal action against Yeater, Braun hinted to Extra. "We've never even seen the lawsuit, but we're going to just get ahead of this thing and go right after it. I think it's important to hold people accountable for their actions."

Added Bieber, who is currently dating Selena Gomez, "We don't want it to seem like it's okay for everyone to say, like, 'I had Justin's baby or [I'm] having his baby.'"
